Summary:PROBLEM TO BE SOLVED: To provide a method for producing aromatic amine solving the problem that, in the case a halogen atom is selected as the well-known leaving group of a coupling reaction raw material compound, since harmful halogen waste is by-produced after reaction, waste liquid treatment is complicated and an environmental load is high and further solving the problem that, in the case a trifluoromethanesulfonyloxy group is selected as the leaving group, an environmental load upon the production of a raw material compound having a trifluoromethanesulfonyloxy group is high, and also, the production operation is complicated.SOLUTION: Provided is a method for producing an aromatic amine compound characterized in that an aromatic nitro compound and an amine compound are brought into cross coupling reaction in the presence of a metal catalyst.SELECTED DRAWING: None 【課題】 従来公知のカップリング反応原料化応物の脱離基として前記のハロゲン原子を選択する場合、反応後に有害なハロゲン廃棄物が副生するため、廃液の処理や煩雑であり環境負荷が高いという課題があった。一方、前記脱離基としてトリフルオロメタンスルホニルオキシ基を選択した場合、トリフルオロメタンスルホニルオキシ基を有する原料化合物を製造する際の環境負荷が大きく、尚且つ当該製造作業が煩雑であるという課題があった。【解決手段】 金属触媒存在下、芳香族ニトロ化合物と、アミン化合物をクロスカップリング反応させることを特徴とする芳香族アミン化合物の製造方法を提供する。【選択図】 なし
